Problem 10
Damaged Compressor Impeller Of The Turbocharger
Probable Cause
1.
The element of the air filter is not sealed correctly. A
connection between the air filter and the turbocharger is
loose.
Inspect the element of the air filter and the air supply
line to the turbocharger for correct installation.
2.
A restriction exists in the tube between the air filter and
the turbocharger.
The component must be repaired or replaced.
3.
The turbocharger is loose or the clamps and bolts on
the turbocharger are loose.
Correctly position the turbocharger and tighten the
damps and bolts.
4.
The flow of the lubricating oil is delayed to the
turbocharger when the engine is started. Insufficient oil
flows to the turbocharger when the engine is running.
Check the following components for correct operation:
oil pump
the engine oil bypass valve
the bypass valve in the oil filter base
oil filter
viscosity of the oil
restrictions in oil lines
5.
The incorrect type of lubricating oil is installed.
Drain the lubricating oil. Replace the oil filter. Install the
correct type of lubricating oil.
